Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability
and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in
the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the
device should not be operated beyond such conditions. All voltages are measured with respect to the ground pin, unless otherwise specified
Note 2: The Electrical Characteristics tables list guaranteed specifications under the listed Recommended Operating Conditions except as otherwise modified
or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not guaranteed.
Note 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by T_JMAX, θ_JA, and the ambient temperature, T_A. The maximum
allowable power dissipation is P_DMAX = (T_JMAX - T_A) / θ_JA or the number given in Absolute Maximum Ratings, whichever is lower. For the LME49610, typical
application shown in Figure 2 with |V_EE| = V_CC = 15V, R_L = 32Ω, the total power dissipation is 1.9W. θ_JA = 20°C/W for the TO-263 package mounted to 16in²
(103.2 cm²) 1oz. copper surface heat sink area.
Note 4: Human body model, applicable std. JESD22-A114C.
Note 5: Machine model, applicable std. JESD22-A115-A.
Note 6: Typical values represent most likely parametric norms at T_A = +25ºC, and at the Recommended Operation Conditions at the time of product
characterization and are not guaranteed.
Note 7: Datasheet min/max specification limits are guaranteed by test or statistical analysis.
Note 8: This is the distortion of the LME49610 operating in a closed loop configuration with an LME49710. When operating in an operational amplifier's feedback
loop, the amplifier's open loop gain dominates, linearizing the system and determining the overall system distortion.
Note 9: The TS5B package is a non-isolated package. The package’s metal back and any heat sink to which it is mounted are connected to the same potential
as the –V_EE pin.
